Application filed January 25, 1922.

i w v 757/75, cones/n: 7 i5; th t i, .l'UmUs iLmnNsTniN, a. iii e of theUnited States, residing at, Jersey City, in the county of Hudson and ofNew Jersey, have invented certain new and useful lniprovements in Door-Closing Devices, of which the following is :1 specification.

vention relates to improvements ices, one of its objects means attachedto the doom to allow the latter i no swung" open, to return to itsorigins]. close position without any further effort or attention.

ll; l'uithe? object: is to provide a device eel-opted replace the usualtype of hinges general use at "the present time, and which use aswing-tor closing the door r it has been opened. These spring s h becomeohjmlionuble on ac- ,F frequent replacements required,

i a or loss of tension. and other objects will become op- .in the'lPSCllptZlOl'l. below in which ring briefly to the mowing, Figure istrout eievotionel 'ieW oi a door and frame as useo on ice boxes orthe'like, closing: device being shown place 1);! lower hinge end.

seotionzil view taken on line it ierspeotive View 01' the roller ;-erilin;z the drawing more in detail, fol l indicates 1L relatively heavydoor of on ice box which when closed, fits snugly into the outwardlytapered opening of The eonsti'uetion mentioned is nsuol, the pui'p-osobeing to prevent, the air 'ithe ico box from reducing the tom- 1 1 tune,by escaping thru the crevices loi'nlcd lie-tween the door and wall. The(loo? is carried on special hinges comprising lined pivot plates 3 whichare secured to the upright l mme member l. These plates have spaced ears5 extending outwardly theireli'oin and adapted to receive hinge heirs o.Bolts 7 fixed in the ears form pivots upon whii'rh the (poor issupported, the ends secured bet-ween cars 7 extending from plates 8permanently e l in horizontal z plates.

Yoke members l0 located centrally on the length of hinge bars 6 formguides and additional means for supporting the door and preventing thesome from so. sing and thus twisti 55 the pivot plates troin the dooror. frame. It door upon his, pci'n'iii; the doc iy into the dooropening. Fla springs 9, se cured between door. uitoce and hinge bars 6in the region of guide yokes 10 urge the door away from the hinge barsand into more intimate contact with the opening, thus insuring a snugfit at all times.

The self closiog-device essentially oomposcd of a channelled frame 1].,is preferably secured in on np ight position to the lower hinge bill bysuitable bolts 12 by passing thru holes iii. t lits 13 out thru the sidewebs of the channelled frame fOlm means for supporting the device whenbeing lifted. An angle iron 14. and anchor hmce l-l, extendingzingulzirly downward, 'floim means for securing the closing oeirice tothe lower door hinge. A. pair of plates 15 secured to the interiorsurtoco of tie frame Wehs at the lower end of the frame 16 by bolts 15,have small lugs 16 which shoulder upon ti o lower edge of the saidframe. A rolls? 1? is rotu tubly mounted between plates 15 upon asuitable spindle retained in position between the 'f :zme Webs. Theroller 1'? is so located us to have its periphery projectsoinowhat belowthe side plates 15, and engages to ride upon an inclined arcuate 4321711track 18, formed upon a. rigid metallic block 19 secured to the floor inan approved manner so that the roller 17 will,

when the door is closed, be riding upon the shallow portof the com track18 as indicated by niuuciul and when the door 1s being" opened, Willride upward upon the orcuate path until the Toilet meets the stop" lug:21 which provides means for limiting the opening or" the door.Uhvioiisly,tho door when being opened will he lift-ed distance equal. tothe perpendicular height of the 0am track 18. For this reason the upperears '5 of the hinge plates are spaced sulliciently apart to permit thisupward movement of the door as the some is being open,

Lil

When 0 ening the door a Common type of spring olt 22 is drawn from thekeeper 9,3, and the door pulled open to the position desired. Inopening, the door will follow the course of cam track 18, the latterbeing of such angle as to overcome any frictional resistance of thehinges and other members which might hold the door open at any position.Therefore as soon as retaining pressure 15 released, the roller willslowly begin. descending, the track, gaining momentum due to the weightof the door which is closed thereby.

I claim:

The combination with a door and its frame, of a closing devicecomprising a pair of hinge bars secured to the door, hinge platessecured to the frame, a pair of spaced horizontal ears extending fromthe frame plates, a vertical pin rigidly supported to extend betweeneach pair of ears, the outer extremities of said bars extending beyondinnate-i the door and being rotatahly supported by said pins as axes,said hinge bars being adapted to rise and fall on said pins between eachpair of ears during opening and closing, of the door, a channelled framesecured in vertical position to the lower hinge bar, a roller axiallymounted at the lower end of said frame between the sides thereof andextending below the lower extremities of said frame, and an areuateinclined cam track secured to the floor heneath the roller, said rollerbeing adapted to engage the lower end of the cam track when closed andto ride upward on said track during opening of the door, the weight ofthe door causing said roller to descend said track when the openingforce on the door has been released, to cause said door to close. y
